It was found that oxirane ring undergoes nucleophilic attack by the primary amine groups of chitosan and the degree of crosslinking increased with increase in curing time, curing temperature and concentration of chitosan.
The antiepileptic drug (AED) vigabatrin, a [gamma]-vinyl analog of the neurotransmitter GABA, appeared the most likely interfering compound because of the presence of a free primary amine and a carboxylic acid within its chemical structure that ninhydrin might label analogously to amino acids.
The Reactions of 2b with formaldehyde and primary amines were subsequently examined under similar conditions and the expected 1-methyl-3-alkyl/aralkyl/aryl-7,7-dimethyl-5-oxo-1,2,3,4,5,6,7,8-octahydroquinazolines 3f-j were isolated in 75-89% yields, whose structures could be established with the help of analytical and spectral data.
It is generally found that the rate constant for reaction of primary amines with aromatic glycidyl ether-type epoxides is approximately twice that of the secondary amine adduct with a second epoxide.
The response of the used biosensor system to cadaverine was 90% of its maximal working range and it was at least 2 times as high as in the case of other primary amines (Table 1).
Small primary amines such as methylamine (MA) react with the thiol-esterified glutamine and induce a nearly identical conformational change in LAM, with a concomitant molecular compaction and activation of receptor recognizability.
Fluorescamine is a non-fluorescent compound that reacts with primary amines to form a highly fluorescent product (Udenfriend et al.

It can be seen from Table-5 that the hydrolyzate obtained by the use of 1% base is composed of primary amines, carboxylic acids, alcohol and phenol.
The results indicated that the predominant concentration of primary amines was consumed via reaction with the epoxy (during cure at 90[degrees]C).
The modest chain extension afforded by the two primary amines in MOD 6 and 8 provide a slight further improvement.
Vulkanox HPG is said to be characterized by a particularly low content of primary amines.
The compound is obtained by reacting at least one hydroxyalkyl ester of an olefinically unsaturated carboxylic acid with two to 12 carbon atoms in the hydroxyalkyl residue with at least one lactone and with at least one hydroxy-functional amine having two to 10 carbon atoms per molecule and where the amino group is selected from the group consisting of primary amines, secondary amines and mixtures thereof and the hydroxy-functional amine is selected from the group consisting of hydroxy functional alkyl amines, hydroxy-functional cyclo alkylamines, hydroxy-functional alkoxyamines and any mixtures thereof; at least one cross-linking agent with functional groups reactive towards active hydrogen and optionally, at least one binder with functional groups containing active hydrogen.
